Summary
Decidual stromal cells (DSCs) exhibit significant heterogeneity and functional changes during labor. These cells play diverse roles in childbirth, impacting pathways related to inflammation and energy balance.
Area of Science:
- Reproductive biology
- Cellular and molecular biology
Background:
- Decidual stromal cells (DSCs) are crucial for pregnancy maintenance and labor.
- Understanding DSC heterogeneity and function during labor is essential for reproductive health.
Purpose of the Study:
- To investigate the heterogeneity of decidual stromal cells (DSCs).
- To characterize functional alterations in DSCs before and after labor onset.
Main Methods:
- Single-cell RNA sequencing (scRNA-seq) was employed to analyze transcriptomic profiles.
- DSCs (6382 cells) were collected before and after labor onset.
- Transcriptomic data were used for cell clustering and pathway analysis.
Main Results:
- DSCs were classified into five distinct subgroups based on transcriptomic profiles.
- Cluster 1 cells were involved in cell substrate adhesion; clusters 2 and 3 were enriched in signal transduction genes.
- Labor onset significantly altered pathways including activator protein 1 and response to lipopolysaccharide.
- Downregulated genes related to coagulation, ATP synthesis, and oxygen homeostasis were observed.
Conclusions:
- Peripartum decidual stromal cells are heterogeneous.
- DSCs exhibit diverse functions and undergo significant alterations during labor.
- These changes may reflect the metabolic and homeostatic adjustments required during delivery.
